Latest Message<\/th>\nTitle: Some admins may receive failures creating or updating Communications Compliance policies in Microsoft Purview <\/p>\n

User impact: Admins may have received failures creating or updating Communications Compliance policies in Microsoft Purview. <\/p>\n

Final status: The fix deployed to the whole of the affected infrastructure, and we’ve confirmed with our internal monitoring telemetry that impact is remediated. <\/p>\n

Scope of impact: Some admins may have received failures when they created or updated Communications Compliance policies in Microsoft Purview with more than four classifiers. <\/p>\n
